APPARATUS FOR LIGHTING AND EXTINGUISHING- GAS-FLAMES.

Specification of Letters Patent.

AppIication filed October 4, 1906.

Patented Aug. 11, 1908.

Serial No. 337,364.

To all whom it may concern:

Be it known that I, JRGEN JAooBsEN, captain, a citizen of the Kingdom of Denmark, residing at Bjergegade 18, Elsinore, Denmark, have invented a new and useful Improvement in Apparatuses for Lighting and Extinguishing Gas-Flames; and I do hereby declare the following to be a full, clear, and exact description ofthe same.

This invention relates to improvements in apparatus for lighting and extinguishing gas at a burner, by means of the pressure oi gas in the conducting system, which can be repeatedly increased and diminished to control the selection of the lanterns to be ignited and extinguished, thus permitting the gasworks to fully manage all of the lanterns, to light all of them or one or several groups of them, and also to extinguish certain groups of lanterns, while other ones remain lighted, and iinally to extinguish the latter ones.

In the drawing, showing a form of the apparatus, Figure 1 represents a vertical longitudinal section through the apparatus; Fig. 2 shows a top view ol the apparatus without the cover and Fig. 3 shows a vertical cross section of the apparatus on the line AB of Fig. 1.

To the casing 1, of the apparatus, is screwed a bottom 3 with a rectangular ringlike continuous canal for receiving quicksilver. This quicksilver is intended to sustain or iioat an inverted reservoir 4, constituting a float which is in connection with a pipe 5 which is in communication with an l opening ,through the top of the float 4. At its upper end, pipe 5 has a connection with pipe 6 which is turnable in a bearing 23, in which there is provided a hollow box 7. Thus the iloat may rise and fall without interrupting the flow of gas through the pipe 5. Upon the float 4 is arranged a chamber 13, in which small-shot and the like can be filled for the regulation of the load of said float. The pipe 6 is discharged by a hole 26 (Fig. 2) into a passage 8, which communicates with a pipe 9, on which a gas-burner is placed. In the bottom, 3, of the apparatus is provided an inlet-opening 2, for the gas.

On the pipe 5 (Fig. 2) is arranged an upwardly and inwardly-disposed angle-arm, 14, bearing a projection 15. In the casing of the apparatus, is a wheel 11 revolving around a pivotal screw. 16. Said wheel has ratchet teeth at its periphery and, at the side, bears a flange, 17, with angular teeth, against which the projection, 15, either strikes or with which same gears according to the position of the float 4. Said 'loat, or (more exactly the reservoir 13) carries a fitting, 18, having a pawl, 10, which turns about a screw 27, and which-when the iloat is liftedan open bottom, and into which the pipe' 37, is arranged to discharge. A passage 29, leads from reservoir 28 to a vertical passage or pipe 24, lat the back of the casing 1, and which is connected at its bottom, by a passage, 30, with the inlet-opening 2, (and the size of which passage is regulated by a screw 25) and its upper end with' a lighting tube. The communication between the pipe, 29, and the pipe, 24, is (Fig. 3) regulated by a screw 31. In the bottom 3 4and the reservoir 38 are (at the back of each) provided dischargingholes, 32, and 33, for quicksilver, and these holes are closed with shutters or the like.

In the upper wall of the casing 1 funnelshaped openings 36 are arranged, through which the quicksilver is illed in.

In order to adjust the cog-wheel 17, for the desired purpose, this communicates with a hand 34 which is arranged on the back of the apparatus and adjusted by means of a spring-pin 35.

When the a paratus is to be operated, the

Quicksilver is illed in until this is discharged through the opening 32, and the lighting ilame is lighted. If the pressure of the supplied gas is increased at the supply station, the float 4 and the pipe 5 will be lifted, whereby the wheel 1 1 is moved. If it is not intended by this pressure, to light the lantern, the cog-wheel must beforehand be constructed or disposed in such way that the projection 15 falls against one of the side teeth of the cog-wheel, and the lantern will then only be lighted after the pressure has been diminished and then again is increased, as the projection, 15, then will fall between two teeth on the cog-wheel. Il it is intended to light the lantern by the 'first increase of the pressure,

the cog-wheel must be constructed in such way that the projection 15 can at once pass through. For a lantern which is to be eX- tinguished by the first diminution of pressure, the interval between the corresponding teeth on the cog-wheel must be so large that the rojection 15 on the way back again can pass etween the side teeth of the wheel. If, however, the lantern is to remain lighted despite the diminution of pressure, the cogwheel must, by its continued rotation during the successive lifting of the reservoir at last show a tooth below the projecting tooth l5, so that the latter, when the reservoir tends to be lowered, will strike against the cogwheel and thus stop the lowering of the reservoir, whereby the introduction of gas is continued without any hindrance. Vhen the necessary higher pressure again is pro duced the wheel will rotate, and by ensuing diminution of the pressure the reservoir can again fall to have the pipe 5 immerse in the Quicksilver, and the inlet of gas is interrupted. When the iioat 4 is lowered the gas will pass through the pipes 27, 29 and 24 to the lighting-flame. It the large lame is to be lighted, the float 4 is lifted and with it the reservoir 38; the pipe 29 will then be imrnersed in the quicksilver in the reservoir 38, and thereby interrupt the inlet of gas to the lighting flame. However, in order to have a small lighting flame burning, while the large iiame is lighted, the aforesaid small narrow communication, 30, is provided between the inlet-opening 2 and the pipe 24, thus automatically assuring that thelighting-flame shall be always burning.

Vhat I claim and desire to secure by Letters Patent of the United States is:

l. In an apparatus for igniting and eX- tinguishing gas at a burner, a easing provided with a burner and having means for supplying gas to said burner and comprising a container for quiclrsilver, a movable float dipping into said container for immersion in the quiclrsilver when in said container, a wheel provided with teeth, a projection carried by the float, and a pawl movable by the float and intermittently operating the wheel to cause the teeth on the wheel to intercept the dipping into said container for immersion in v the quiclrsilver when in said container, a ratchet wheel having peripheral teeth and equidistant teeth upon one of its sides,i a pawl movable by the float and engaging with the peripheral teeth of the wheel for intermittently moving the latter, and a projection carried by the loat and movable into engagement with or between the side teeth of said wheel.

3. In an apparatus for igniting and eX- tinguishing gas at a burner, a casing provided with a burner and having means for supplying gas to said burner and comprising a gas inlet to the lighting iiame, a container for quicksilver, a movable Boat dipping into said container for immersion in the quiclr'silver when in said container and a reservoir carried by said float and containing a body of quicksilver to close the aforesaid gas inlet, in combination with a wheel having teeth and with a projection carried by the float and movable into engagement with or between the teeth of said wheel.

In testimony whereof, I have signedmy name to this specification in the presence of two subscribing witnesses.

JRGEN JACOBSEN.
